AUTOMOBILE HAND-JACK HANDLE.

Application filed April 14, 1923. sum in. 632,008.

To all whom it may) concern:

Be it known that I, JOSEPH J. 'MIZER, a citizen of the United States,residing at Racine, in the county of Racine and btate of Wisconsin, haveinvented certain new and useful Improvements in Automobile H and-J ackHandles, of which the following is a specification.

an interior view of the reduced and retracted portions of the resilientsleeve member.

My invention relates to separable handles for'automobile jacks, whichmay be detached from the jack, folded and stored in small space.

It is an object of my invention to provide a detachable hinged foldinghandle for an automobile jack having a distinctive resilient membertoexert a spring and g pping action upon the other parts the handle tohold said hinge from folding when the device is in use.

Another object of my invention is to provide a detachable folding handlefor an automobile jack of a collapsible and readily detacliable formwherein the various parts will not uickly wear out or become loosened,and whic combines efiiciency .with strength, durability, lightness, andlow manufacturing)cos t. v ther objects and advantages of the inof thefollowing description.

In he accompanying drawings-forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

F1 1 is a longitudinal side-view in' er spective of a handle for anautomobile Jack embodying my invention, in an extended or operableposition, the dotted lines showing how the parts may be folded.

Fig. 2 is an enlarged sectional view taken along the line 2-2 of Fig. 1,showing an end view of the resilient sleeve member.-

Fig. 3'is a top plan view of an embodi ment of my invention showing theopen sideof the resilient member, and the u set rectangular end of oneof the longitudinal members for introduction into a suitable socket inthe jack.

'Fi 4 is a bottom plan view showin reduced and retracted portions in theresl ient sleeve member.

Fig. 5 is a central longitudinal sectional view taken along the line 5-5of Fig. 3, showing means for securing the longitudinal members to theresilient sleeve member, and

. rotatin In the drawings, wherein for the purpose of illustration isshown a preferred embodiment of my invention, the numeral 10 designatesa resilient member in the form of a channel or split sleeve. tionoft-his member 10 has a flat base and substantially parallel sideportions 12. These side portions .12 converge slightly toward oneanother near their ends as at 13. These converging ends 13 are furtherretracted or curved toward one another where they join at the end of thebase as at 11, to provide additional ipping elements for the members 15and 16 as hereinafter described.

Pivotally secured bet-ween the central side portions 12 of the member 10by any-suitable means, such as rivets 18, are the lon tudinalsections.15 and 16 of thehan e.'

' hers 15 audio re'ac fully extended position. The sprang 'rippf actionthus increases progressive y' as t e -members are moved to o erativeposition, and looseness or play-in t 0 arts is prevented. The exteriorend 19 o the longitudinal member 15 is upset for a substantial distanceso as to The central pore form a rectangular portion 20 suitable forinsertion in a corresponding socket inthc jack. For a substantialdistance along its exterior or free end the longitudinal member 16 isbent to, form an approximately T-shaped handle portion 22.-

Assuming the rectangular end portion 20 I to be inserted in the socketof a jack, -the two longitudinal members havin first been swung awayfromeach other, or ivergently until in line witheach other, in whichposltion the reduced and retracted portions of the resilient member orsleeve are in frictional contact with them, upon grasping and the handleportion 22, the jack screw is actuated and the jack raised or lowered.

The handle may be readily removed from" i the jack socket and completelyfolded or closed by bringing the two-longitudinal members in completecontact with each other; The handle may then be readily stowed away.

My invention eliminates the trouble and inconvenience caused by looseand easily worn joints of the common type in automobile jack handles ofa rotatable and folding character.

The device may be rapidly and cheaply manufactured out of any suitablematerial, such as ordinary commercial steel, giving desired strength andservice with a minimum amount of material. I

So far as I am aware I am the first in the art to provide a collapsiblehandle comprising a bar and a member having side portions in convergingspaced relation pivotall connected with the bar inposition to e swung tobring the side portions into resilient gripping engagement with oppositefaces of the bar, whereby as the bar and the sideportions ot the memberare worn in use efiiective gripping may be ef-' fected by a veryslightly" increased pivotal movement for jamming the bar to an increasedextent into the grip of the convergent side portions.

I claim:

1. A folding handle comprising a bar formed in two sections, a clip inthe form of a channel member having a base, and central substantiallyparallel side portions between which the adjacent ends of the barsections are pivoted, the ends of the sideportions of the clipconverging toward one another into gripping relation with the barsection therebetween, the space between the gripping end portionsdecreasing away from the open side of the channel, so as to provide aprogressive ripping action on the bar section as it is orced into thechannel. 2. A folding handle comprising a bar formed in two sections,'and a clip in the form of a channelmember having a base,

therebetween and provide an additional gripping means for the barsections.

JOSEPH J. MIZER.
